Plant & Equipment
K&J Civil operates a modern, well-maintained fleet of plant, transport vehicles and specialist attachments purpose-suited to water and sewer infrastructure projects across Queensland.
Our equipment supports works including SGATE valve installations, live cut-ins, trunk mains and urban utility construction, and is operated exclusively by experienced, ticketed personnel. All plant is maintained under strict servicing schedules to meet safety, reliability and authority compliance requirements, including those of Queensland Urban Utilities (QUU) and Unitywater.
Plant & Equipment Summary
The table below provides a high-level overview of the core plant and equipment regularly deployed on K&J Civil water and sewer infrastructure projects.
Category | Equipment | Typical Application |
|---|---|---|
| Excavators | 34T Excavator | Heavy excavation, deep trenching, large-diameter pipelines |
| 20–25T Excavator | Utility trenching, pipe installation | |
| 12–13T Excavator | Urban trenching, medium cut-ins | |
| 7.5T Excavator | Road crossings, restricted access | |
| 5T Excavator | Confined space and service works | |
| Transport | 16T Tipper | Bulk material haulage |
| Hook Bin Truck (4 bins) | Spoil removal and site clean-up | |
| 10T Bogie Tipper | Medium-load haulage | |
| Attachments | Hydraulic Hammers (3.5T–34T) | Rock and concrete breaking across excavator fleet |
| Support Plant | Bobcat / Backhoe / Roller | General site works and reinstatement |
| Buttwelding | Typical application | Used to join two metal pipes or plates end-to-end to create a strong, seamless connection in structural and pipeline applications. |
Plant selection and configuration are project-specific and aligned with access constraints, live service conditions and authority requirements.
How Our Plant Supports Utility Construction
Our fleet is selected to support live environments and authority-regulated assets, not general civil earthworks.
Capability tie-ins include:
- Excavators → trenching, live cut-ins, valve and SGATE installations
- Tippers & hook bins → spoil removal, traffic-sensitive haulage
- Attachments → pavement, concrete and rock removal
- Support plant → reinstatement and finishing works
This alignment between plant and methodology improves safety, programme certainty and installation quality.
Excavators & Site Plant
Our excavator fleet covers a wide range of sizes to suit varying trench depths, access constraints and pipe diameters.
Typical applications include:
- Deep trenching for trunk mains
- Urban water and sewer reticulation
- Live cut-ins and valve installations
- Confined access service works
Plant is selected based on constructability, safety and efficiency, not convenience.
Transport & Logistics Fleet
Efficient spoil management and material movement are critical on utility projects, particularly in road corridors and urban environments.
Our transport fleet supports:
- Bulk and medium-load haulage
- Controlled spoil removal
- Site clean-up and reinstatement
- Rapid mobilisation between sites
Hook bin configurations are selected to suit site access and disposal requirements.
Attachments & Specialist Equipment
Specialist attachments allow works to be completed safely and efficiently without unnecessary over-excavation.
Attachments support:
- Rock and concrete breaking
- Pavement removal
- Utility trench preparation
- Controlled demolition works
Attachments are matched to excavator size and task-specific requirements.
Maintenance, Safety & Compliance
All plant and equipment used by K&J Civil:
- Is maintained in accordance with manufacturer and regulatory standards
- Is inspected prior to mobilisation
- Is operated by trained and ticketed personnel
- Is integrated into project-specific safety plans
This ensures reliability during live works and critical utility interfaces.
Proven Use on Live Utility Projects
Our plant fleet is actively deployed on complex utility projects across Queensland, including:
- Indooroopilly – live SGATE valve installations in traffic-sensitive environments
- Stevens Road – staged live cut-ins with controlled excavation and reinstatement
These projects demonstrate our ability to deploy the right plant, at the right scale, in live and constrained environments.
Why Plant Selection Matters
Correct plant selection directly affects:
- Safety outcomes
- Programme performance
- Quality of installation
- Authority acceptance
Our fleet is purpose-built to support water and sewer infrastructure, not generic civil works.
